NGN in Korea
• BcN (Broadband convergence Network) is a term generally used in Korea
for NGN.
• Definition & Goal of BcN
– Next Generation Convergence Network integrating communication, broadcasting
and Internet and providing QoS-enabled multimedia services anywhere, anytime,
and by any means (source: BcN Forum, Korea)
– Goal: Constructing core /network infrastructure for realizing Broadband IT Korea
by building Broadband converged network
• 20 million subscribers(50~100 Mbps) until year 2010
• Scope
– Open API, End-to-end QoS, Security, IPv6
– MPLS, DWDM, OXC
– FTTH, HPi, WLAN, DMB, HDTV, RFID, Ubiquitous access
• Requirements for BcN
– Features necessary for supporting Integrated Home network, Broadcasting,
Multimedia contents and communications are added to the general requirements
for NGN.
• NGN requirements at ITU-T (source: JRG-NGN)
– IP connectivity independent underlying transport layer, Access independence,
Roaming and nomadism, Open service environment, Evolution path from legacy
network to NGN, Enhanced security, Separation of call and bearer control, Call
and session control based on IETF
Convergence of fixed and mobile

Issues for discussion and collaboration
•
Current NGN standards do not fully take into account the current environment where
services are converged.
– NGN call control related
• Signaling & API: IETF, ITU-T SG11, Parlay
• Architecture: ITU-T, 3GPP/2, ETSI, …
• Interoperability: MSF, IMPP, …
– Home Network related
• ECHONET, HAVi, HomePNA, HomeRF, UPnP, UWB, ..
– Broadcast related
• OpenCable, T-DMB, S-DMB, DVB-T, …
– Fixed-Mobile convergence related
– HPi, Mobile IP related
– AAA, QoS, Security issues in convergence environment
 Wholistic approach in standards setting is required
•
Call control is well defined but content, data (streaming) and broadcast control are very
little touched upon in current NGN standards.
 Collaborations among SDOs are required.
•
•
Enhanced functional architecture is required for converged service environment.
Interoperability among different service platforms are also necessary for integrated
services.
 Cooperation in Interoperability test needs to be encouraged among SDOs.
